Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a fixture for fixing various members used for traction therapy in appropriate positions such as a bed.

(Prior Art) When performing traction treatment in orthopedics on a bed, for example, a tower is constructed on the bed as shown in Figure 5a, or a support is placed on a footboard as shown in Figure 5b. are installed, and members such as pulleys are fixed to such towers and supports. Conventionally, such members have been fixed by tightening screws, as shown in FIG. 5 above.

(Problems to be Solved by the Invention) This type of screw-tightening type has problems in that it is relatively troublesome to operate, and is prone to wobbling and is unstable.

The present invention aims to solve this problem.

(Means for Solving the Problems) Figures 1 to 4 show the configuration of the present invention corresponding to embodiments.
To explain based on the drawings, the present invention has a first recess 3 on the outside of the fixture body 2 of the towing device member 1.
A fastening member 5 having a second recess 4 opposite to the first recess 3 is fixed to the fixture main body 2 so as to be openable and closable, and an operating lever is provided on the opening/closing side of the fastening member 5. 6 is rotatably provided, a female thread member 25 is rotatably provided on the base side of the operating lever 6, and a male thread portion 24 is formed at one end of the tightening rod 7.
is screwed into the female threaded portion of the female threaded member 25 to rotatably support the tightening rod 7 with respect to the operating lever 6, and the other end of the tightening rod 7 and the fixture main body 2 are provided with: The operating lever 6 has corresponding engaging portions 8 and 9, and when the engaging portions 8 and 9 are engaged, the operating lever 6 has a line of action 10 of the force of the tightening rod 7. The operating lever 6 is configured to be rotatable up to the tightening member 5 side from the rotation fulcrum 11 of the operating lever 6.

(Operation) The present invention having the above configuration operates as follows.
First, when the engaging parts 8 and 9 are not engaged, the tightening member 5 can be opened and closed freely, and thus the inside of the fixed part formed by the first recess 3 and the second recess 4 is Supports 12, horizontal beams 13, etc. can be positioned at.

Thereafter, as shown in FIGS. 1a and 2b, the operating lever 6 is separated from the tightening member 5, the engaging parts 8 and 9 are engaged, and then the operating lever 6 is tightened. When rotated to the attachment member 5 side, the tightening member 5
The opening/closing side gradually moves toward the fixture body 2, and thus the first recess 3 and the second recess 4 are connected to the support 12.
etc. gradually tighten. As the operating lever 6 is rotated in this way, the line of action 1 of the force on the tightening rod 7
0 eventually exceeds the pivot point 11 of the operating lever 6 and reaches the side closer to the tightening member 5 than the pivot point 11, as shown in FIGS. 1b, 2b, and 3. Therefore, the operating lever 6 is toggled and held on the side of the tightening member 5 by the tightening rod 7, and thus the tightened state of the support column 12 and the like by the first and second recesses 3 and 4 is maintained.

If the diameter of the support column 12 etc. is small and the tightening is loose,
Turn the tightening rod 7 to adjust the screwing position of the male threaded part 24 to the female threaded part 25, and adjust the screwing position of the tightening rod 7 from the position of the female threaded part 25 to the engaging part 8 at the other end. By adjusting the length to be shorter, the space of the fixing part can be narrowed and sufficient tightening force can be obtained.On the other hand, if the diameter of the support 12 etc. is too large to tighten, the above-mentioned method can be used. By adjusting the length of the tightening rod 7 involved in tightening, it is possible to perform tightening with an appropriate tightening force.

In the present invention, as described above, the towing device member 1 can be easily adjusted to support the pillars 12 of various diameters.
etc., with an appropriate tightening force, and can be easily removed by reversing the operation described above.

(Embodiment) To further explain the illustrated embodiment, the configuration shown in FIG. It is supported in a hanging state. Further, in the configuration shown in FIG. 4b, the traction device member 1 is a pulley 14 as in the case of a, and this is connected to the fixture main body 2.
It is supported in a downwardly hanging state via a suspension ring 15 from the tip of a support rod 16 protruding in the lateral direction. Next, the configuration of the lower side of FIGS. 1 to 3, FIG. 4c, and FIG. 4e is as follows:
As shown in FIG. As shown in FIG. 4c, this presser member 19 is used to press the pipe member 17 from above, as shown in FIG. 4e.
Reference numeral 9 denotes a support member 2 configured in the lateral direction of the fixture main body 2.
It is attached to a support rod 22 that can be moved up and down by the rotation of a lever 21 provided at 0. Furthermore, the configuration shown in FIG. 4f is such that the towing device member 1 is a support 23 for fixing the various towing device members 1 as described above, that is, the fixing device main body 2 is attached to one end of the support 23. It is installed. Furthermore, the configuration shown in FIG. 4g is such that the towing device member 1 is the fixture itself of the present invention, that is, a pair of fixture bodies 2 are connected back to back to constitute a pair of fixtures, and thus the above-mentioned It connects the pillars 12, horizontal beams 13, etc.

(Effects of the invention) As described above, the present invention provides a toggle type fastening member that forms a second recess that constitutes a fixing part together with the first recess of the fixture main body, using a tightening rod and an operating lever. The fixing device is actuated and held by the main body of the fixing device, and this action attaches the towing device member to the struts, horizontal beams, etc. that make up the towing device, so it is easy to operate and can be fixed stably without wobbling. effective.

Furthermore, since the length of the tightening rod for the above-mentioned holding can be adjusted in the present invention, it has the advantage that it can be attached to columns of various diameters with an appropriate tightening force.
